friend painted my car. 4 tries to get the flat black hood right. wanted something with a clear. first attempt dried with while spots and streaks in it. ez followed directions to a "t". second attempt with a different flattening agent in the clear resulted in shiny spots. third attempt, with yet again a different brand of flattening agent looked like there was no flattening agent mixed in. he gave up and just sprayed it flat black, no clear. looking back at it we should have just got the ridiculously expensive right stuff and been done with it....
